I think it was filmed and that he came round a corner at speed, lost control of his care and if the driver of the other mini hadn't taken instant action to avoid, a head on collision would have occurred . I don't understand the minimisation of this incident. If you look at the cars involved, the damage clearly indicates speed was a real factor.
If my three year old grandchild had been in the other car, fearful and weeping, I'd have been so very cross even if the driver who caused the collision hadn't been under the influence of alcohol because they were obviously driving too fast for the road conditions.
